Already the world’s largest exporter of sulphur, Abu Dhabi continues to expand its sour gas production and sulphur output.

CRU expects sulphur prices to be supressed in early 2024 by high port inventory and limited phosphate export business. However, affordability continues to support raw materials purchases and leaves room for price increases, especially if downstream production picks up as expected and sulphur stock drawdown slows.

Urea. As February ended, urea prices found support in the US and Brazil while Europe remained subdued and Egypt struggled to find buyers. New Orleans was the one bright spot in the urea market – with NOLA prices benefitting from the meeting of suppliers and buyers at the TFI’s domestic conference. With positive sentiment all round, prices moved up $30/st, peaking at $390/st f.o.b. for March.

Pyrite roasting as a source of sulphuric acid continues to be a significant, albeit minor sector of the overall acid market.

Cobalt-molybdenum (CoMo) catalysts are integral components of tail gas units (TGUs), playing a vital role in reducing harmful sulphur dioxide (SO2 ) emissions arising from Claus sulphur recovery units. Effective activation of these catalysts is essential for their optimal performance. The consequence of sulphiding at low temperatures and atmospheric pressure in low temperature TGUs is to compromise effectiveness of catalyst activation. In the first part of this two-part article, Michael Huffmaster , Consultant, explores CoMo catalyst activation at low pressure, focusing on sulphiding reaction pathways and the impact of temperature and the composition of the sulphiding media on reaction kinetics, specifically the concentration of H2 , H2 S, and H2 O.

US domestic oil production has surged during 2023, reaching 13.3 million bbl/d in December, a record not just for the US but for any single country’s oil production. Adding in natural gas liquids and biofuels takes overall liquids production to 21.4 million bbl/d. Exports are also running at record levels, around 6 million bbl/d. This is a remarkable turnaround from 2008, when production was less then 5 million bbl/d and exports essentially zero. Furthermore, non-OPEC production is continuing to expand, with Brazil reaching 3.4 million bbl/d of oil production and 4.2 million bbl/d of liquids, and Canada producing 4.8 million bbl/d of crude and 5.7 million bbl/d of total liquids, keeping oil prices moderated in spite of OPEC+ production cuts. Global oil production is expected to reach a record level in 2024, with non-OPEC+ liquids growth projected to increase by 2.7 million bbl/d, far more than demand growth of 1.6 million bbl/d. n

Small quantities of sulphur in a refinery or gas feed can present challenges for conventional large scale sulphur recovery techniques.

Sulphur prices declined in Q4 following the increases seen during Q3, because of ample availability and limited spot demand. One contributing factor was that phosphate fertilizer producers in China, the largest importer of sulphur, have cut downstream production due to increased export restrictions. In addition, high sulphur stocks at Chinese ports and continuing high domestic sulphur production mean that domestic buyers have other options aside from international purchases.

Sulphur prices are expected to increase during H1 2024, reversing the trend of recent declines, though good availability will limit the upside to price gains in the short term. However, should fertilizer production prove weaker than expected, prices may remain below expected levels.

Axens has developed a new titania-based catalyst named CRS 41, which has a much larger porosity than its renowned predecessor, CRS 31 catalyst. Thanks to an improved catalyst manufacturing process and a new recipe, the porosity of CRS 41 has been increased while preserving the mechanical resistance for loading, allowing customers to optimise their capex by either reducing the Claus reactor size or loading volume of TiO2 catalyst.
